A self-climbing system, in particular a self-climbing formwork system, comprising at least one climbing rail which is guided on at least two climbing shoes, in particular an upper and a lower climbing shoe, wherein the climbing shoes can be fastened on and/or on top of a cured concreting section, and an actuator. A circulating drive means is arranged along the climbing rail, at least over a length portion of the climbing rail, can be moved relative to the climbing rail by means of the actuator and can be selectively blocked or unlocked in the region of a climbing shoe and/or in the climbing shoe by means of at least one fixing device. Furthermore, a method for operating a self-climbing system according to the invention. The invention opens up an improved climbing principle for self-climbing systems whereby, for example, continuous climbing becomes possible.

A forming system includes a frame and two forming walls. The two forming walls are positioned at a distance from each other to define a first vertical wall course. One forming wall is supported by the frame such that the one forming wall can be translated toward or away from the respective other forming wall. The frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical course. The translation of the one forming wall allows for the pouring of the first vertical course with horizontally extending rebar that extends through the one forming wall outside of the first vertical wall course, to tie in to a subsequently poured floor slab. The translation permits the vertical raising of the one forming wall, without striking the extending rebar, to pour the second vertical course on the first vertical course. A worker's platform is provided that is supported by the frame and vertically movable by raising the frame. The worker's platform is located below the one forming wall on a side of the one forming wall opposite the respective other forming wall and is retractable to also clear the extending rebar during raising of the frame.

Embodiments of positioning systems and methods are disclosed herein. Embodiments of such positioning systems may include a hierarchy of positioning systems. Each of the positioning systems in the hierarchy may be adapted to move each positioning system lower in the hierarchy along with one or more end-effectors. A control system may control the positioning systems of the hierarchy using a control method comprising a coarse step, a refinement step, or an adaptive step.

A load-bearing structure and a method of producing a load-bearing structure, in particular a tower of a wind energy plant, provides a hollow concrete part with an outer wall which is manufactured by several layers produced in wet-on-wet technology. The outer layer is a fine-grain concrete layer provided with a textile reinforcement, and the inner layer is made of bulk concrete.
